Posterior tibial artery access using transradial techniques: retrograde approach to inaccessible lower extremity lesions.

Percutaneous intervention of chronic limb ischemia is often limited by vascular access especially in patients with previous surgical interventions. This warrants development of alternative endovascular techniques, particularly for patients in whom traditional ipsilateral antegrade or contralateral retrograde access has failed or is not possible. We describe a novel approach to the posterior tibial artery using retrograde access with transradial techniques including closure devices in two patients with inaccessible antegrade access. © 2011 Wiley Periodicals, Inc.
